The nonradiative transition costs follow the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace premiums is https://riverjpwjk.blogdanica.com/33097470/a-secret-weapon-for-er-yb-yab-crystal
